iPod - Ipod won't connect with firewire

I've been using my 5.5 ipod 80gb on a windows pc for about 10 months but have recently converted to a macbook pro. One of the flaws of it though is the lack of usb ports so i thought i'd use firewire to connect the ipod however when i plugged it in, it said it didn't support firewire for transferring songs.

I've searched and can't find anything so any help would be really appreciated!
thanks
